대황 모상근 추출물의 세포독성
Abstract
The purpose of this research was to investigate the effects of extracts from cultured hairy roots of R. undulatum on human kidney epithelial cells. Hairy roots were induced by a co-culture with A. rhizogenes ATCCl5834 and cultured in WPM medium. The cytotoxicity was measured by colorimetric assay using 3-(4,5-dimethythiazol-2-yl)-2,5- diphenyl-2H -tetrazolium bromide (MTT), neutral red (NR) and sulforhodamine protein B (SRB) with human kidney epithelial cell lines A498. MTT, NR and SRB quantities decreased propotionally in cultured A498 cells treated with the water or chloroform extracts of cultured hairy roots at increasing concentrations. These results suggest that extracts of cultured hairy 개ots are cytotoxic on human epithelial cells. The cytotoxicity of chloroforrm fraction was stronger than that of water fraction. The values of
배양된 대황으로 모상근으로부터 추출한 물질에 대한 분획별 신장상피세포에 있어서의 세포 독성을 조사하였다. l 수층과 클로로포름 층으로부터 얻은 대황 모상근 추출물모두 농도의 증가에 따라 세포에 미치는 독성이 증가하였다. 2. 클로로포름층으로부터 얻은 대황 모상근 추출물이 수층으로부터 얻은 대황 추출물보다 세포에 미치는 독성이 크게 나타났다. 콜로로포름층 분획의
